Jenifer Jayme

Jen joined Big Brothers Big Sisters of the Bay Area as Vice President of Development in November 2016 and has volunteered as a Big Sister for nine years.She brings 18 years of extensive experience in fund development and youth-serving organizations.

Jen has previously served in development leadership roles at the Hispanic Scholarship Fund, St. Vincent de Paul Society, Santa Clara University Center for Science, Technology & Society, Techbridge (a national nonprofit devoted to STEM education for underrepresented girls), and university, high school and elementary educational institutions (UC Berkeley, and independent Montessori, Waldorf and Catholic schools).

Jen gained invaluable experience over seven years as a fundraising consultant to nonprofits, where she worked with and learned from high net worth donors, veteran fundraisers, and extraordinary boards and leaders at a broad range of philanthropic organizations. At San Francisco-based Laura Talmus Associates, and at the international firm Community Counselling Service (CCS), Jen worked with leading nonprofits on development audits and capital campaigns, including the National Partnership for Women and Families, the Astronomical Society of the Pacific, the Oregon Province of Jesus (Jesuits), the Nature Conservancy of Washington, and Sacred Heart Medical Center.

Jen was raised in government housing in East Boston by a single mother who went from welfare to being a homeowner/landlord and first in her family to earn a college degree.Jen’s career in philanthropy was shaped by childhood years in an inner-city neighborhood of concentrated poverty followed by high school years in affluent Marin County, California, and the stark contrast in opportunities and culture she experienced between those communities. She has a passion for racial and gender equity, and deep interest in youth development and trauma-informed care rising from personal experience, avid reading, parenting a young child, and growing up in a family of social workers and therapists.

Jen earned a B.A. in English with Honors from U.C. Berkeley. She lives in Novato with her husband and 8-year-old son, and enjoys snowboarding, reading, tinkering, and leading arts and crafts activities at her son’s elementary school.
